ADUs vs. short-term rentals in Brant
No local short-term-rental law on record - which is not the same as permission for Town of Brant. No local short-term-rental law found for Town of Brant as of 2026-08-06; absence of a found law is not permission. New York State's 2025 STR registry (Ch. 99 of the Laws of 2025) separately requires every host statewide to register through the Erie County registry. Confirm with the building department at (716) 662-8378 before listing. These are separate questions from whether you can build an ADU — a unit you're allowed to add isn't automatically one you're allowed to rent nightly, so check both.
